Description
Technical field
The utility model relates to a kind of surface cooler, is specifically related to a kind of central air-conditioning end-equipment with ultra-thin draught fan coil pipe surface cooler.
Background technology
At present, the development trend of the surface cooler of fan coil is under the situation of the certain exchange capability of heat of maintenance, makes the volume miniaturization and saving cost of surface cooler as far as possible, thereby forms ultra-thinization, lightweight fan coil.The size of the exchange capability of heat of surface cooler depends primarily on the selection of U-shaped pipe radical and the shunt of arrangement, water knockout drum and water collector; Volume size that the selection of U-shaped pipe radical simultaneously and arrangement have also determined surface cooler and material how much; The mounting means final decision of whole surface cooler the whole height of indoor set be the cost problem.
The surface cooler of traditional fan coil normally is provided with perpendicular to the installation of fan coil chassis; If will form ultra-thin type, mainly be to realize through the height that reduces fan coil, and owing to surface cooler vertically is provided with; When reducing the fan coil height; Certainly will will reduce the height of surface cooler, then the consumption of fin and U-shaped pipe all can reduce to some extent, so can influence the whole exchange capability of heat of this type to a great extent.
In addition, the surface cooler of traditional fan coil generally comprises 2 rows or 3 row's U-shaped tubular constructions, and the caliber of U-shaped pipe is bigger; Be generally Φ 9.52 or Φ 7.94, because the restriction of surface cooler for fan coil height, water knockout drum, water collector are generally 2 the road or 3 the tunnel; The simplest chilled water stream is to be divided into 2 the road or 3 the tunnel from the bottom to advance; Converge again at the top, promptly comprise 2 or 3 chilled water channel units, form 2 and advance 2 and go out or 3 advance 3 streams that go out.With double U-shaped manage-style coiler surface cooler shown in Figure 1 is example; It is laid mode and places for vertical; U-shaped pipe caliber is Φ 9.52; Water knockout drum, water collector are 3 the tunnel, comprise 3 chilled water channel unit A (frame of broken lines is selected part among the figure), and each chilled water channel unit A includes 1, chilled water outlet 2 and two row of a chilled water inlet totally 3 U-shaped pipes 3; Chilled water inlet 1 in this unit first arrange the U-shaped pipe that portion holds inlet; Chilled water outlet 2 in this unit second arrange the U-shaped pipe at top outlet, the outlet of each U-shaped pipe is communicated with through 90 ° of elbows 4 with the inlet of its different row's adjacent U-shaped pipe, the inlet that the U-shaped pipe of bottommost is arranged in the outlet and second of the U-shaped pipe of as shown in Figure 1 first bottommost arranged is communicated with through 90 ° of elbows 4; The outlet of the U-shaped pipe of second row's bottommost is communicated with through 90 ° of elbows 4 with the outlet of the U-shaped pipe of first row's bottommost; Chilled water gets into from the chilled water inlet 1 that is positioned at first row's bottommost, from second arrange top chilled water outlet 2 flow out, the chilled water flow direction is shown in arrow among Fig. 1.Existing this fan coil when low number, can also satisfy the requirement of high energy efficiency; When but heat increased, because U-shaped pipe caliber is bigger, chilled water channel unit quantity was few; The flow process of chilled water increases in each unit, and the drag losses of chilled water is increased, and causes heat exchange efficiency to reduce.
Moreover, the surface cooler of existing fan coil, general whole employing fissure types of its fin or plain film formula, windage is bigger, thereby makes exchange capability of heat descend, and heat exchange efficiency is lower, if will improve heat exchange efficiency, then can increase the consumption of fin and U-shaped pipe, and cost strengthens.
